Transferring gamer profiles between U.K/Jap 360's & Gamerscore

[Escape-To-88]

Hi all,
I'm picking up a jap console from a mate of mine he longer wants for a bargain 50 bones. I'm not getting a HD with it but everything else. I don't want to take this unit online so will use it offline to play some of the japanese exclusive shooters.
My question is, can I copy my gamer profile from my uk elite to a memory card and use it between machines e.g switch back and forth?
Secondly, can I use the profile on the japanese unit, then switch back to my UK elite (which is online) and upload/add to my gamerscore? Or will tis switching of profiles between consoles, racking up gamerscore on one console and effectivey transfer it, buggerup my LIVE access in some way?
Cheers

I currently have a flashed PAL unit, standard PAL unit and a JP unit and my profile stays on my memory card. I use it on all 3 systems without a problem, so you'll be fine.

You does everyone mess about with memory cards?
Just use the HDD instead. So much easier as the space on a MC cannot hold all my DLC etc.
Just plug your HDD onto which ever x360 your using at the time. I've 5 x360s around the house and this is the method I use.

I only have 2 machines I use so for me, it's no hassle as all my save files go on the card whilst DLC stays on the machine it was downloaded on. PAL stuff on the PAL system, Jap stuff on the Jap system.
